Abstract
Energy conversion efficiency is a key index to evaluate microwave wireless energy transmission system, which indicates the capacity to transform microwave energy into direct current (DC) energy. In this paper, the primary component of the rectifier circuit design, Ge Schottky Diode (SBD), is optimized and designed from a structural standpoint in the context of wireless energy collection in the weak energy density of 2.45 GHz Wi-Fi band, with the aim of enhancing the efficiency of the rectifier circuit in the presence of weak Wi-Fi energy density. The PSPICE parameters of the designed SBD were extracted using the parameter extraction tool, and the Spice model of the developed SBD was built. Utilizing this model, the rectifier circuit was simulated using ADS to enhance its efficiency and confirm the effectiveness of the intended devices. The findings indicate a notable enhancement in the energy conversion efficiency of the new Ge Schottky diode within the weak energy working region.
